摘　　要：本系统以超低功耗的MSP430F169单片机为核心,包含角度检测模块、直流电机调速模块、声光提示模块、键盘及显示模块、电源模块等。通过输出PWM波的占空比去控制直流电机的转速,直流电机带动风扇使帆板与垂直平面形成一定的夹角,通过角度检测电路得到帆板的实际角度值,两者之间不相等而产生角度偏差。系统通过PID控制修正该偏差,使角度稳定到规定的范围内,实现对帆板角度的精确控制。The system take ultra low power consumption MSP430F169 MCU as the core, containing the angle detecting module, DC motor speed control module, an acoustic-optic prompting module, keyboard and display module, power supply module and etc. This system uses the output PWM wave duty cycle to control the rotation speed of the DC motor, DC motor drives the fan to make the panels and a vertical plane form an angle.Through angle detection circuit receives the actual value of the angle of panels, The two angle is not equal to produce angle deviation. The system uses PID method correcting the deviation, so that the angle stability to the specified range, to achieve the precise control of panels angle.
